Scale bars
Scale bars provide a visual indication of the size of features and distance between features on the map. A scale bar is a line or bar divided into parts and labeled with its ground length, usually in multiples of map units such as tens of kilometers or hundreds of miles.


Scale bar elements
When the scale of the data frame changes, the scale bar will automatically be updated to reflect the new scale. For scale bars to be displayed correctly, it is important that the map units property for the data frame is set.

Scale Bar - A map element which shows the scale of a map graphically.
Set - A group of features and their data.
Spatial - (pro. Spay-shawl) An adjective. Of, relating to, or occurring in space.

Scale Bar - A map element used to graphically represent the scale of a map. A scale bar is typically a line marked like a ruler in units proportional to the map's scale.

scale barA map element that shows the map scale graphically.
scanningThe process of capturing data in rasterformat with a device called a scanner. Some scanners also use software to convert raster data to vector data.

the ~ will remain correct
the written Statement of Scale will not be correct ...

Creates a scale bar frame - inserts a scale bar that corresponds to the view, scale is in the map units specified in the view
Creates a north arrow frame - inserts a correctly located north arrow ...

Warning: The scale bar after it has been inserted to the map is linked to the data frame, so if you zoom in or otherwise change the scale of the data contained with the Data Frame it will change accordingly. However, after you convert it to graphics it is not.

To change the scale bar units to "meters," click on the pointer button , which is the first button on the left in the second row of buttons at the top of the screen.
Double-click on the scale bar in the Layout. The Scale Bar Properties dialog box appears.

~ - Is a visual expression of the relationship between ground coordinate space and that if the map page space. (Clarke, 2001)
Select feature tool - The Select Feature tool lets you select features with the mouse by pointing at them or by dragging a selection box over them.

[map design] The arrangement of elements on a map, possibly including a title, legend, north arrow, scale bar, and geographic data.
[ESRI software] In ArcGIS, a presentation document incorporating maps, charts, tables, text, and images.
[ESRI software] In ArcView 3.

Titles, Legends, Scale Bars, and North Arrows are all forms of Map Annotation. Functionally they are used to depict information concerning the map. The various programs available usually handle this as user input and the software does not generate it.

These maps will typically include standard information such as a title, north arrow, scale bar, corporate contact information, data source, and so forth. This is simple if the site is small enough that the pertinent mapped features can be resolved on a single map.

It is usually printed on the map to the left of the scale bar at the bottom of a USGS 7.5' quadrangle. After finding the declination on the map, you need to transfer the information to your compass before you ever take it into the field.

Templates can contain data, a custom interface, and a predefined layout that arranges map elements, such as north arrows, scale bars, and logos, on the virtual page. Map templates have a .mxt file extension.

It may also contain additional graphical elements such as scale bars, north arrows, text, images, and geometric shapes (drawing objects). If you are familiar with any presentation graphics program, such as Microsoft Powerpoint, then creating and modifying layouts will be easy to learn and to do.

Make sure you transfer at least the large-print portion of the UTM grid markings onto the photocopy. It's also helpful to provide scale and contour information. Preprinted scale bars on Post-It note paper are available or just make a copy of the scale bars and "cut and paste" ...

Specifies location and size of elements (viewports, scale bar, north arrow, legend) in a map sheet.
plot template block
An AutoCAD block that contains plotting information such as title page text, plot layouts, legend, and other map annotation.

For example, a map element can be a title, scale bar, legend, or other map-surround element. The map area itself can be considered a map element; or an object within the map can be referred to as a map element, such as a roads layer or a school symbol. [Category=Geospatial ] ...

Next we will create a map layout for our greater context map. We will add a title and a scale bar some text that labels our are of interest. We will take a look at legends.

An important property of a map is the scale. It can be indicated by a scale bar and/or a ratio 1:n. This enables the map user to measure a distance on the map and determine the distance on the ground.

a map of scale 1:50,000 shows a distance of 50,000 cm (=500 m) as 1 cm on a map, and a model on a scale 1:25 of a building with a height of 30 m has a model height of 1.20 m. An alternative method of indicating the scale is by a scale bar. This can also be applied on a computer screen etc.

Remove all information from the map that is not essential. Common pitfall: drawing attention first to a utility element such as a large or centrally placed scale bar or north arrow, or an overlarge legend; or, hiding the title in small fonts.
